Marcus Bernard Williams was sentenced to death for the 1997 rape and murder of his neighbor Melanie Rowell, whom he strangled and sexually assaulted after breaking into her home while her two toddlers slept nearby. Eighteen days later, Williams committed another sexual assault, leading to his arrest and eventual confession to Rowell's murder. The Alabama trial court found one aggravating factor—murder during rape and burglary—which it deemed to outweigh mitigating evidence about Williams's troubled childhood.

Writing for the panel, Circuit Judge Grant explained that Alabama sentencing courts "generally weigh the aggravating circumstances of his crimes—burglary, rape, and murder—more heavily than the kinds of mitigating evidence he offered, including episodic, unreported childhood sexual abuse." The court emphasized that federal habeas courts must follow the Supreme Court's guidance in Thornell v. Jones, which requires weighing evidence "in the same way that the state sentencing judge and appellate courts would have done," rather than conducting an independent analysis.

Williams had successfully argued in federal court that his trial attorneys provided ineffective assistance by failing to investigate and present evidence of childhood sexual abuse and family instability. A federal judge granted habeas relief in 2021, and the Eleventh Circuit initially affirmed in a split decision in 2023. However, the Supreme Court vacated that judgment and remanded for reconsideration in light of Thornell, which clarified how federal courts should analyze prejudice in capital sentencing cases.

The reversal reinstates Williams's death sentence and reflects a more restrictive approach to habeas relief following Thornell. Circuit Judge Wilson dissented, arguing that the majority's interpretation "unfairly erodes the critical Sixth Amendment right to effective assistance of counsel" by requiring federal courts to defer to state court preferences rather than conducting independent constitutional review. The case highlights ongoing tensions over the scope of federal habeas review in capital cases.
